3	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4	>	all previous copies of the IBX source code tree before installing this release.
5	>
6	>	The IBX packages used by most users have not changed, with one exception. The
7	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8	>	to use the IBServices unit in your applications, please add the iblegacyServices
9	>	to the list of dependencies. To do this, open the Project Inspector and select
10	>	Add->New Requirement and select "ibLegacyServices" from the list of available
11	>	packages.
12	>
13	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14	>	the IBServices unit providing what is intended to be a clearer and easier to
15	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
16	>	more information and the guide to "Firebird Service Management Using IBX".
17	>	As indicated above, the legacy services components are still available and
18	>	provided in a separate package. There is no need to update working applications
19	>	using the older versions except for an additional package dependency.
20	>
21	>	2. The IBX packages and source code tree have been re-organised in an attempt to
22	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
23	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
24	>	new set of IBX packages.
25	>
26	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27	>	updated to use the new Services API components.
28	>
29	>	4. The iblocal package has been updated to use the new Services API components.
30	>
31	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32	>	TIBXSecurityService. It had been wrongly classified in the previous version
33	>	as a per database configuration item. It is global to a server and hence
34	>	correctly positioned as part of the Security Package. In the DBAdmin example,
35	>	the setting has moved to the mappings page.
36	>
37	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38	>	are ignored.
39	>
40	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41	>	closed before the database is dropped. Before and After Disconnect event handlers
42	>	are also fired.
43	>
44	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45	>	is started and not just the first time.
46	>
47	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48	>	depenendency with comp type.
49	>
50	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51	>
52	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53	>	then this is recognised and not ignored.
54	>
55	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
56	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
58	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59	>
60	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
61	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
62	>	counters for the select query. Note: stats accumulate after each fetch from
63	>	the database. To get total query cost after open, call the "Last" method
64	>	and then GetPerfStatistics.
65	>
66	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67	>
68	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69	>	in parenthesises.
70	>
71	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72	>	SQL identifiers are always delimited by double quotes. If false, then they are
73	>	only delimited if the identifier is a reserved word, contains lower case or special
74	>	characters. Set this property to true to retain previous behaviour.
75	>
76	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78	>
79	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
80	>	property MasterDetailDelay: integer {defaults to zero}
81	>
82	>	When non-zero and the dataset is a detail table referencing a master table
83	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84	>	then a synchronisation delay is added (in milliseconds) between the master
85	>	row changing and the detail dataset being re-opened. If the master dataset
86	>	is scrolled before the delay expires then the delay is reset. This can be used
87	>	to avoid performance overheads when scrolling through a large master dataset.
88	>
89	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
90	>	chreads unit must be included in your project. TTimer is not used in order
91	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92	>
93	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94	>	with Extract Option eoDatabase.
95	>
96	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97	>	When a deLayoutChanged event is reported on the ListSource dataset, the
98	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99	>	relationship with the control's datasource (master).
100	>
101	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102	>
103	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
105	>
106	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107	>	DDL (Firebird 3 and later only).
108	>
109	>	22. TIBLookupComboBox Autocomplete Fixes:
110	>	i. Only appended text is now selected after autocomplete.
111	>	ii. Uppercase keys no longer ignored for autocomplete.
112	>	iii. Retain Prefix case is now honoured correctly.
113	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114	>	before autocomplete performed. i.e. behaviour now the same as when
115	>	no DataSource assigned.
116	>
117	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118	>	between SQL statements.
119	>
120	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121	>	ObjectNames are converted to upper case before matching against metadata object
122	>	names, unless the objectname is delimited by double quotes, in which case, the
123	>	double quotes are removed and the remaining string is used (unmodified) to match
124	>	against the metadata object name.
125	>
126	>	If true then the ObjectName is used as is without modification and matched
127	>	against the metadata object name. No attempt is made to remove double quotes.
128	>
129	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130	>	with eoTrigger, these extract types can be used to select only Database Triggers,
131	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132	>
133	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
134	>	statement separate character is now reset to the default (';').
135	>
136	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
137	>
138	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
139	>	a commit or reconnect statement and instead activated only when next SQL statement
140	>	is executed.
141	>
142	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
143	>
144	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
145	>	converting statement to upper case.
146	>
147	>	31. TIBExtract: metadata comments now supported. New published property
148	>	IncludeMetaDataComments (default true). If true then metadata comments included
149	>	in extracted DDL. New Extract Object member eoComments. This may be used with
150	>	ExtractObject method to list all metadata comments.
151	>
152	>	32. TIBExtract: ListObjectNames method added.
153	>
154	>	33. Updated Database component editor to support additional connection string
155	>	types.

177		a returning clause that updates one or more fields on the current row. A full row
178		refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
179		field values and the select query contains read only fields. Use of Insert/update
180	<	returning should be significantly more efficient than excuting a refresh query.
180	>	returning should be significantly more efficient than executing a refresh query.
181
182		This behaviour change is intended to be backwards compatible and there should be no need to change
183		existing programs, other than to improve performance by using the new capability.

186	>	they are called when the dataset row is being deleted, there is no value in
187	>	updating the current record from the query result. Instead, a new event handler
188	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
189	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
190	>	by the query. The event handler can then interrogate the query results and
191	>	perform whatever action is necessary. For example to confirm, to the user,
192	>	the deletion of a row with the returned values.
193	>
194	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
195		any Computed By or Identity Columns. The IBTables example has been updated to
196		illustrate the computation of the employee Full Name on update.
197
198	<	4. TIBTable: The GeneratorField property is now published.

200	<	5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
200	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
201		When InsertSQL is generated, the Identity columns are not included in the list of values to
202		be inserted. A RETURNING clause is added to the insert statement to return the value of
203		each Identity column after the insert is executed.
204
205	<	6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
205	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
206		Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
207		Insert..Returning clause.
208

217	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
218		values are no longer converted to milliseconds from TDateTime and then back again
219		to TDateTime (the conversion to milliseconds is the default TDataset approach).
220
221	<	11. Property Editors handling of Stored Procedures.
221	>	12. Property Editors handling of Stored Procedures.
222		* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
223		which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
224		query).
225		* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
226
227	<	12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
227	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
228		can be used to select a package. If non-empty, the stored procedure name is
229		expected to be a stored procedure defined in the specified package and the
230		generated SQL will be as required for a stored procedure located in a package.
231
232	<	13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
232	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
233		a "Package Name" drop down box to allow selection of a Firebird 3 Package from
234		which a stored procedure can be selected. With no package name selected, non-package
235		stored procedures are listed.

237	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
238		for password on reconnect.
239
240	+	16. TIBDatabase: use IAttachment for connection default character set id, code page
241	+	and character set name.
242	+
243	+	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
244	+	DB info lookups"
245	+
246	+	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
247	+
248	+	19. Add a property Editor for TIBUpdate.RefreshSQL.
249	+
250	+	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
251	+	parameters. This stops an exception being raised when the field cannot be
252	+	located in the record buffer.
253	+
254	+	21. Property Editors now automatically include System Tables when opened and when the query table
255	+	is a System Table.
256	+
257	+	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
258	+	This avoids errors due to a stale SQRB or SRB being used for the next query.
259	+
260	+	23. IBServices: Service attach parameters now include "expected_db". This is used to
261	+	add the SPB item isc_spb_expected_db. This names a database using
262	+	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
263	+	database. examples/services re-written to illustrate use of "expected_db".
264	+
265	+	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
266	+	This avoids truncated backups when the server returns a timeout (busy) response.
267	+
268	+	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
269	+
270	+	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
271	+	databasenames. These are respectively expanded to the local system's temp directory
272	+	(including trailing delimiter) or to a prescribed data directory (including
273	+	trailing delimiter). Under Unix systems the data directory is a hidden directory
274	+	in the user's home directory. The hidden directory name is either the string returned
275	+	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
276	+	Under Windows, the directory is the same as the Data Directory as decribed
277	+	above but instead prefixed by the User's application data path. These may be
278	+	used to improve application portability for Personal Databases.
279	+
280	+	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
281	+	this has not worked for a long time and is not useful either. FieldDefs should be
282	+	managed using the Fields Editor as with any other dataset. To access the fields
283	+	editor for a TIBTable component, double click on the component. The fields editor
284	+	is then displayed.
285	+
286	+	28. TIBDatabaseInfo: new properties/function
287	+	* DateDBCreated (returns date/time database created)
288	+	* TransactionCount (returns no. of active transactions)
289	+	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
290	+	* PagesFree (Firebird 3 or later)
291	+	* PagesUsed (Firebird 3 or later)
292	+	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
293	+	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
294	+
295	+	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
296	+
297	+	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
298	+
299	+	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
300	+	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
301	+
302	+	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
303	+	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
304	+	firing during backup and restore.
305	+
306	+	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
307	+	for verbose output using the new property "StatisticsRequested".
308	+	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
309	+
310	+	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
311	+
312	+	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
313	+	palette. This uses the online validation feature added in Firebird 2.5. The
314	+	services's properties enable inclusion/exclusion of tables and indexes using
315	+	regular expressions. See.
316	+	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
317	+
318	+	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
319	+	option on a database.
320	+
321	+	37. TIBCustomService: Assign method implemented to allow copying of service login
322	+	context between service API components. "Detach" method now only detaches
323	+	service when last reference to the service interface detaches. Tidy up of
324	+	code for SetActive and Attach methods including password hiding.
325	+
326	+	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
327	+	and used to determine the auth method and protocol used for the connection.
328	+
329	+	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
330	+	a Create Database Statement generated by IBX.
331	+
332	+	40. All IBServices now have an additional published property "PortNo". This may
333	+	be set to a non-standard port number when necessary. If zero then the default
334	+	port number is used.
335	+
336	+	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
337	+	and not just the mouse.
338	+
339	+	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
340	+
341	+	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
342	+	image index and selected image index for each node to be set from a database field.
343	+
344	+	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
345	+	then database schema includes grants to all users. If not present then the
346	+	only user grants included are those to User PUBLIC.
347	+
348	+	45. TIBTreeView: performance improvement. When expanding include both expanded node
349	+	and child nodes in dataset.
